The electrochemical treatment of dyestuff from aqueous solution using an iron cell was achieved with reduction in chemical oxygen demand (COD) and color with high efficiency. Degradation of the azo dye Reactofix Red 3 BFN was carried out under different experimental conditions. Electrolysis completely decolorizes the effluent with substantial reduction in COD value. The rate kinetics during electrolysis was found to be first order. Results show that electrochemical reduction is a superior technology for treatment of dyes, as there is no simultaneous addition of anions, such as sulfate or chloride.
使用铁电池对水溶液中的染料进行电化学处理，可高效降低化学需氧量（COD）和颜色。在不同实验条件下对偶氮染料Reactofix Red 3 BFN进行了降解。电解使废水完全脱色，COD值大幅降低。发现电解过程中的速率动力学为一级。结果表明，电化学还原是一种处理染料的优越技术，因为无需同时添加硫酸根或氯离子等阴离子。
